摘要：
A burner (40) having a transition zone (46) to act as a buffer between the primary zone (42) and the secondary zones (48, 50). The transition zone (46) allows improved control of near-burner mixing and flame stability by providing limited recirculation regions between the primary zone (42) and the secondary zones (48, 50). These limited recirculation regions transport evolved NOx back towards an oxygen-lean pyrolysis zone near the burner exit (52) for reduction to molecular nitrogen, thus decreasing emissions and unburned fuel losses.
